"DDA will soon come up with a policy defining the financial and non-financial initiatives to be offered to those who live in green buildings. The policy will set a precedent for development of 'smart cities' across the country," Sanjiv Kumar, Secretary Environment and Forest, Delhi Govt said while addressing the Delhi Environment Summit here today.

Elaborating on the policy draft, Dr Prem C Jain, Chairman India Green Business Council said, "While the non-financial initiatives include benefits additional floor space index the financial ones are likely to include some waiver in property tax or lower property tariffs.

"The government has assured us support in this regard and agencies other than DDA will also help implementing the green building culture in all the areas."

"We any way need dumping grounds for low cost compost and the by product sells around Rs 10 per kg where as if we use sewage treatment plans and use it to produce CNG, it will sell around Rs 60 per kg," she said.

"Similarly the building constructions should also involve the use of micro-simulators which ensures useful utilisation of waste as resources," Lekhi added.
